Electrical Installation 115 VAC

7.Screw strain relief (6b) into electrical cover (2a).

8.Position power cable (6c) so the large diameter of power cable extends through strain relief (6b).

9.Tighten nut on strain relief to form a seal around the power cable.

10.Reinstall electrical cover (2a) on the pump.

11.Remove 1/2 in. (13 mm) of insulation from wires on the fuse holder end of the power cable.

12.Attach battery clamps (6a) with red sleeve to red wire and black sleeve to black wire. Wire must be crimped to the battery clamp firmly to get a good electrical connection.

13.Connect red wire with fuse holder inline to positive battery terminal. Connect black wire to negative bat- tery terminal.

Electrical Installation 115 VAC

On 115 VAC pumps, electrical connections must be made by a licensed electrician per requirements of local, state, and national codes regarding class 1, group D installations. Only rigid conduit with threaded connections should be used. Conduit opening in pump must be sealed with waterproof, herbicide-resistant sealant. Failure to comply with this warning could result in injury from electrical shock.

1.Ensure pump switch is OFF and electrical power is disconnected.

2.Install conduit and user-supplied power cord to pump.

3.Strip 3 in. (76 mm) from power cord jacket and 1/2 in. (13 mm) from individual conductor insulation.

4.To remove electrical cover (2a), remove four bolts (2c).

5.Remove 1/2 in. (13 mm) of insulation from power wires inside pump electrical terminal cavity.

Installation

6.Insert electrical power wire through conduit opening in back of pump.

7.Using wire nuts (2e), connect wires: green to green, white to white, and black to black.

8.Replace electrical cover.

Priming Pump

1.All pump models will prime with no fluid in the pumping chamber to a height of 5 ft (1.52 m). If pump fails to prime, remove hose from street elbow fitting on pump outlet and pour 8 oz (0.24 liter) of motor oil into the pump outlet port.

2.If suction height is too great, the pump may lose its prime if the nozzle is opened with the pump turned off.

3.To hold fluid in the suction tube, a check valve (Graco Part No. 260217) may be required on the bottom of tanks with a suction height over 5 ft (1.52 m).

4.The tank must be vented or the pump may not prime or may lose its prime due to a vacuum in the tank.
